About Ficus pumila 'Minima'

Ficus pumila 'Minima' · also called Miniature Creeping Fig · houseplant

Ficus pumila 'Minima' is a miniature creeping fig with especially tiny, neat green leaves, prized for terrarium and bonsai-style use. It clings with aerial roots and forms a fine, dense mat. Keep the soil consistently lightly moist, give bright indirect light, and maintain good humidity, as this small-leaved fig drops foliage quickly if it dries out.

Cold limit: USDA 9-11 (indoor in most US and UK homes; tender outdoors) · RHS H2 (15-24°C)

Watch for — Rapid leaf drop: The classic creeping-fig response to the rootball drying out, cold draughts, or abrupt relocation. Keep moisture even, avoid draughts, and leave it settled in one spot.

What ficus pumila 'minima''s hardiness rating actually means

Ficus pumila 'Minima' is half-hardy (RHS H2). It survives a mild winter outdoors in a sheltered spot, but a hard frost kills it — so in colder zones it is lifted, potted, or grown as a tender plant. Its RHS rating of H2 means: Tender — survives a frost-free greenhouse or a very mild, sheltered spot. On the US scale that maps to USDA 9-11 (indoor in most US and UK homes; tender outdoors) — the zones where it can be left outdoors year-round.

New to these scales? The USDA hardiness zone map explained covers how the zone numbers work, and you can find your own zone with the zone finder.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about 1 to 5 °C — tolerates cold but no real frost. Ficus pumila 'Minima' shrugs off cold nights but a real, sustained freeze will kill it.

Concretely, for ficus pumila 'minima' as it gets too cold:

Down to roughly about 1 to 5 °C it copes, especially if dry and sheltered.
A sustained hard frost collapses the top growth; whether it returns depends on whether the roots, crown or tubers froze.
Wet cold is far more lethal than dry cold for this plant — soggy, frozen soil is the usual killer.

Can ficus pumila 'minima' go outside or overwinter — and where?

It can live outside year-round only in the mildest, most sheltered part of USDA 9-11 (indoor in most US and UK homes; tender outdoors) or a frost-free UK microclimate.
In colder zones, grow it in a pot you can move under cover, or lift its tubers/roots and store them frost-free over winter.
A south-facing wall, free-draining soil and a dry winter position can push it a full zone hardier than the books suggest.

Work back from your local frost dates with the frost-date calculator: the last spring frost and first autumn frost are what really decide when ficus pumila 'minima' can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H2 figure above.

Frost protection for borderline ficus pumila 'minima'

Ficus pumila 'Minima' is right on a hardiness edge in many gardens, so if you are pushing it, these measures buy it the margin it needs:

Mulch the crown or root zone deeply with bark, straw or leaf-mould before the first hard frost.
Move container plants against a warm wall or into an unheated but frost-free porch or greenhouse.
Fleece the top growth on the coldest nights, and keep it on the dry side — dry roots survive cold far better than wet ones.
Lift dahlia-type tubers or tender crowns after the first light frost blackens the foliage and store them somewhere cool but frost-free.

Ficus pumila 'Minima' hardiness — frequently asked questions

Is ficus pumila 'minima' cold hardy?

Ficus pumila 'Minima' is half-hardy (RHS H2). It survives a mild winter outdoors in a sheltered spot, but a hard frost kills it — so in colder zones it is lifted, potted, or grown as a tender plant. Borderline outdoors. In its mild end of USDA 9-11 (indoor in most US and UK homes; tender outdoors) (and sheltered UK gardens) ficus pumila 'minima' can stay out; in colder areas it must be lifted, brought in, or treated as a frost-tender plant.

What is the minimum temperature ficus pumila 'minima' can survive?

Minimum survivable temperature is roughly about 1 to 5 °C — tolerates cold but no real frost. Ficus pumila 'Minima' shrugs off cold nights but a real, sustained freeze will kill it.

What hardiness zone is ficus pumila 'minima'?

Ficus pumila 'Minima' is rated USDA 9-11 (indoor in most US and UK homes; tender outdoors) and RHS H2 — Tender — survives a frost-free greenhouse or a very mild, sheltered spot.

Can ficus pumila 'minima' survive winter outside?

It can live outside year-round only in the mildest, most sheltered part of USDA 9-11 (indoor in most US and UK homes; tender outdoors) or a frost-free UK microclimate. In colder zones, grow it in a pot you can move under cover, or lift its tubers/roots and store them frost-free over winter. A south-facing wall, free-draining soil and a dry winter position can push it a full zone hardier than the books suggest.

How do I protect ficus pumila 'minima' from frost?

Mulch the crown or root zone deeply with bark, straw or leaf-mould before the first hard frost. Move container plants against a warm wall or into an unheated but frost-free porch or greenhouse. Fleece the top growth on the coldest nights, and keep it on the dry side — dry roots survive cold far better than wet ones. Lift dahlia-type tubers or tender crowns after the first light frost blackens the foliage and store them somewhere cool but frost-free.
